Where is the secondary structure in collagen? Because secondary dtructure is present when there is alpha helix, collagen has no alpha helix but an overall helical structure. In mark schemes its written it has a secondary structure? Should it have quaternary due to presence of 3 polypeptides?

a triple helix is collagen secondary structure, although I think this is not in the syllabus, you just need to say helix, since all active proteins have secondary structure

I think so, because a tertiary structure is a subunit whereas a quaternary is a complete unit, it is like Lego bricks i guess

Do we need to remember the name of scientists in As Biology? For example Singer and Nicolson presented Fluid Mosaic model so do we need to remember their name?
